The Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1), where the negatively charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits, is accompanied by an emitted or absorbed amount of electromagnetic energy (hν).

Mechanical vapor recompression (MVR) is an energy recovery process which can be used to recycle waste heat to improve efficiency. [1] [2] Typically, the compressed vapor is fed back to help heat the mother liquor in order to produce more vapor or steam.
A sphere rotating around an axis. Points farther from the axis move faster, satisfying ω = v / r.. In physics, angular frequency (symbol ω), also called angular speed and angular rate, is a scalar measure of the angle rate (the angle per unit time) or the temporal rate of change of the phase argument of a sinusoidal waveform or sine function (for example, in oscillations and waves).
Paul Nahin, a professor emeritus at the University of New Hampshire who wrote a book dedicated to Euler's formula and its applications in Fourier analysis, said Euler's identity is "of exquisite beauty". [8] Mathematics writer Constance Reid has said that Euler's identity is "the most famous formula in all mathematics". [9]

The turn (symbol tr or pla) is a unit of plane angle measurement that is the measure of a complete angle—the angle subtended by a complete circle at its center. One turn is equal to 2π radians, 360 degrees or 400 gradians.
In physics, the gyromagnetic ratio (also sometimes known as the magnetogyric ratio [1] in other disciplines) of a particle or system is the ratio of its magnetic moment to its angular momentum, and it is often denoted by the symbol γ, gamma.
It is an intermediate in the redox-related pair C 6 H 5 NH 2 and C 6 H 5 NO. N -Phenylhydroxylamine should not be confused with its isomer α-phenylhydroxylamine or O -phenylhydroxylamine. Preparation
